Abstract

Provided is an oral care composition comprising a peroxide source, a polyhydric alcohol and a surfactant system having an HLB value of from 4 to 13, wherein the combined amount of the polyhydric alcohol and the surfactant system is from 60 weight % to 95 weight % by total weight of the composition, and wherein the weight ratio of the polyhydric alcohol to the surfactant system is from 9:1 to 1:4.

       9. The composition of  claim 8 , wherein the weight ratio of the polyhydric alcohol to the surfactant system is from 3:2 to 1:1. 
     
     
       10. The composition of  claim 1 , wherein the combined amount of the polyhydric alcohol and the surfactant system is from 70 weight % to 95 weight % by total weight of the composition. 
     
     
       11. The composition of  claim 1 , wherein the combined amount of the polyhydric alcohol and the surfactant system is from 80 to 90 weight %, by total weight of the composition. 
     
     
       12. The composition of  claim 11 , wherein the combined amount of the polyhydric alcohol and the surfactant system is from 85 weight % to 90 weight % by total weight of the composition. 
     
     
       13. The composition of  claim 1 , wherein the surfactant system having an HLB value from 4 to 13 comprises a non-ionic surfactant. 
     
     
       14. The composition of  claim 13 , wherein the surfactant system having an HLB value of from 4 to 13 comprises propylene glycol monocaprylate. 
     
     
       15. The composition of  claim 1 , wherein the surfactant system having an HLB value of from 4 to 13 comprises sorbitan laurate. 
     
     
       16. The composition of  claim 15 , wherein the surfactant system having an HLB value from 4 to 13 comprises polyethylene glycol caprylate/caprate glyceride. 
     
     
       17. The composition of  claim 1 , wherein the peroxide source is selected from: hydrogen peroxide, urea peroxide, sodium percarbonate, sodium perborate, polyvinylpyrrolidone-hydrogen peroxide complex, and mixtures thereof.
